Patent number: 6328621Abstract: Method and apparatus for manufacturing an electron gun. A beam spot coefficient is obtained from an electrostatic lens magnification and a spherical aberration coefficient of a set resistance distribution. Then, a first process loop is executed to select another resistance distribution that provides an approximate minimum value of the beam spot coefficient. It is then determined whether the beam spot coefficient is an approximate minimum value. The first process loop is repeatedly executed until the beam spot coefficient is determined to be equal to the approximate minimum value. At this point, a second process loop is executed to confirm the minimum value of the beam spot coefficient using an aberration-independent function that is dependent upon the electrostatic lens magnification and is not dependent upon the spherical aberration coefficient.Type: GrantFiled: May 1, 2001Date of Patent: December 11, 2001Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Masatoshi Kudoh, Ryuichi Murai, Mitsuhiro Ohtani, Katuyoshi Yamashita, Hideharu Ohmae, Masahiko Konda

Patent number: 6329843Abstract: A current driver, a common mode voltage monitoring circuit and a current compensator are provided to drive a twisted pair cable, which is made up of two signal lines coupled to a terminal bias voltage through respective terminal resistors. The common mode voltage monitoring circuit monitors a difference between a common mode voltage of the twisted pair cable and a supply voltage level for the current driver. And the current compensator is coupled to the twisted pair cable to compensate for an output current of the current driver in accordance with a result of monitoring performed by the common mode voltage monitoring circuit. If the current driver has decreased its current drivability due to a drop of the supply voltage level of the current driver or a variation in the common mode voltage of the twisted pair cable, then the current compensator compensates for the decrease. Thus, the current driver can continuously operate in a broad voltage range to supply a constant current.Type: GrantFiled: October 10, 2000Date of Patent: December 11, 2001Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Takashi Hirata, Hironori Akamatsu, Satoshi Takahashi, Yutaka Terada, Yoshihide Komatsu
